I read the review. Mr Francis detailed some of the problems he had with the game (and, of course, the problems of its online nature), but all in all the review was a very positive one. He loved the feel of combat. He loved the skill system. He loved the class diversity. He loved the way it looked. He loved the monster design.
He summed it up by saying it was "...
a phenomenally good game, immediately fun to play and enduringly compulsive." Diablo has "never been such spectacular fun to play, or so creative to tinker with." Would he recommend it to a friend? He'd make them aware of the connectivity issues, and then: "God, yes."
I recognise scores tend to do more harm than good, although I hold a degree of affection for them, and in the hands of good reviewers I find them quite useful. Surely if any review reads as a 90% it's this one. It certainly fits in with how I remember PCG UKs scoring system to work.
Besides that, Tom nailed exactly how I feel about the game. I love what he loves and I have issues where he has issues.
